Microsoft tools receive constant updates and are more future-proof than legacy programs
Standard programs such as Excel, Word and Outlook are part of daily work. They should be migrated as a priority.
Microsoft's diverse tools are often underestimated or unknown, despite their helpful capabilities.
Departments such as accounting or secretarial services are particularly dependent on functioning spreadsheets in Excel.
Department-specific requirements should be handled cohesively, so one is not overwhelmed by constantly changing specifics.
Especially important as well as API files with special scripts should be secured as a precaution and checked for functionality after migration.
The 5 most common mistakes when migrating to Microsoft 365
1. Old and new systems are operated in parallel
Employees constantly need double user logon, which is often perceived as a nuisance
2. Schedule cannot be realistically estimated
When setting a schedule, the first difficulties usually become apparent. Schedules do not always run best case and buffer times should be planned for contingencies.
3. The order of the individual steps is not observed
The migration starts with a clean setup of the tenant. Many migrations start randomly and data loss occurs. Even small errors can have major consequences.
4. Obtaining a data overview
In order to be able to determine after the migration whether data losses are present, one should compile a data overview beforehand
5. Employees are not trained for new system
Employees should be informed about the migration. Employees should also be made aware of important new features. This is the only way to prevent major teething problems.

Do you know these problems? If you do, Microsoft 365 helps you out!
Office version differences lead to problems
Employees complain that files don't work as they should, or document sharing results in view errors.
Overview of user licenses incomplete, outdated or not available at all
License purchases are years behind and are assigned in a confusing manner. With the Microsoft 365 Admincenter you have the complete system clearly displayed, with variable license management.
Employees don't like to switch to a new system every few years
Many new features with major version jumps every few years can be disruptive for clarity and productivity. With the automatically updating system, the changes are mostly small and happen piece by piece.
Microsoft 365 to replace your on-premises Exchange Server
Exchange Server 2013 will reach its end of life support on April 11, 2023. The migration from Exchange 2013 to Microsoft 365 or Exchange 2019 is therefore imminent and should be planned now. If you do not migrate your Exchange Server in time, you are taking a high security risk. After the support end date, Microsoft shuts down its security services for the servers. Since the support end date is public, hackers can react promptly.
